My country of origin is variously listed on TT4 as Canada or Unknown. It is, in fact, Canada and there's no question about this at all. My mother is just a phonecall away so I can ask her to be sure, but the Province of BC agrees with me, I've had at least 3 Canadian passports in my life and I've never had a reason to think otherwise. And I haven't left the country or renounced my citizenship or been even REMOTELY bad since the switch to TT4, so I'm pretty positive I'm still Canadian and not persona non grata.
Another Canadian I know now has his country of origin listed as Bulgaria. An American whose posts I'd searched a few weeks ago, last time I looked, her country of origin was listed as Uzbekistan.
There seems to have been some sort of slippage with the transfer, and certain settings slid down to the next slot or up to the one above. DianaHaddad talks about this above. At least, I THINK it was DianaHaddad, but I can't just scroll up and check with the new system! Which irritates me MUCH more than having my country of origin listed as Lower Moldavia or something.
So, no, it's not just you. It's a bit like a giant game of geographical musical chairs. Be kinda fun if we COULD all just go to the country we're purportedly from.
